If pig production is profitable, lowering the mortality rate improves net income. However, it can be difficult to determine what cost can be incurred to lower the mortality rate and achieve a profit. The purpose of this fact sheet is not to determine the cost of mortality mitigation strategies but to help producers determine the income opportunity of improving mortality in their operation as compared to the potential cost of a strategy to lower mortality. Mortality reduction strategies and costs will most certainly vary among operations and situations.
Part 1 focuses on the non-infectious factors contributing to mortality, and their magnitude of impact.
Part 2 focuses on the infectious factors that contribute to post-weaning mortality in the swine industry.
In this video, Dr. Edison Magalhaes from the Iowa State University College of Veterinary Medicine explains his research on whole herd drivers of wean-to-finish mortality. He develop an automated statistical model to capture and merge multiple data streams into a single cohort report. Then, he used that cohort report to measure the association between specific parameters and wean-to-finish mortality as well as forecast closeout mortality based on multiple variables.
